DABING IVEECHANISM FOR WOOL-'COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 391,567, dated October 23, 1888.

v Application filed July 1l, 1887. Serial No. 243,962. v(No model.) Patented in England .Tune 2G, 1885, No. 7,797, and in France December 16, 1885, No. 173,046.

To all whom it may concern.:

Be it known that I, FRED. UNWIN, residing at Brussels, Belgium, have invented a new and useful Improvement in Dabbing Mechanism for VooLOombing Machines, (for which I have obtained patents in England` No. 7,797, bearing date June 26, A. I). V1885, and in France, No. 173,046, bearing date December 26, 1885,) of which the following is a specifica` tion.

My invention relates to the use of blades either alone or in combination with brushesin lieu ofthe ordinary dabbingbrushes for pressing the Wool into the inner and outer combs of Nobles coinbinginachines. It has been proposed to employ such blades with a compound motion imparted to them, such that the entire blade was raised out of the comb and was moved somewhat in the direction of the movement of the comb while descending into the same. 0

According to one of my present improvements', I arrange the blades to Work on aXed fnlcrum at one end in such a position that such ends of the blades are always maintained within the outer comb, while the other ends of the blades, which are curved upward, are connected to an eccentric, crank, or cam, whereby they are alternately raised and lowered so as to press the liber into the comb as it advances toward the blades. By this arrangement the fiber is kept well in the combs as it passes under the blades, and cannot be drawn out again by the action of the dabbingbrush on the fiber in the inner comb, while at the same time there is no risk of the blades coming in contactwith the points of the comb and thus damaging the same, such as might occur when the entire blade is raised clear of the comb, as heretofore.

The dabbingbrush for pressing the liber into the inner comb, instead of being actuated by the same eccentric as works the blades, as

was formerly the case, is worked by an independent eccentric, crank, or cam, and in combination therewith I employ a fixed blade situated within theiuner comb behind the dabbingbrush, so that as the fiber is pressed into the comb by the brush it at once passes underneath the said blade, and is thus effectually retained in the comb thereby.

Reference is to be han Vto the accompanying drawings, forming a part of this specilication, in which similar letters of reference indicate corresponding parts in both the iigures.

Figure l 0f the accompanying drawings shows a front view, and Fig. 2 a side view, of part of a Nobles combingmachine with my above-described improvements applied thereto.

The pillar A carries a bracket, B, in which is mounted a. spindle, C, having a grooved pulley, D, driven from a pulley, E, by an endless band, as shown. The outer end of the spindle C carries a crank, C', which is connected by an adj estable rod, F, to tlie blades G, which are curved on their under sides and pivoted at G to the arm B on the bracket B, so that by the rotation of the crank an upand down motion is imparted to the front curved end of the blades G, so as to alternately raise them out of the outer comb, H, and depress them into the comb, while the back parts of the blades always remain in the comb. rPhe blades are partly supported by a helical spring, I, connected to the bracket B. By curving the blades G on their under sides at their forward ends, and by pivoting them upon a fixed pivot at the heel, the wool is depressed into the pins by two actions-viz., the up and down motion of the blades and the depressing due to the motion of the wool carried against the lower curved edges of the blades. This enables theblades to be worked wholly within the pins. The spindle C also carries an eccentric, J, the rod ot' which is connected to the upper end ofthe bar K, carrying the dabbingbrnsh K', that is constantly moved in and ont of the inner comb, L, by the action of the eccentric. Behindthedabbing-brushisarranged a plate, M, situated within the inner comb, L, in which position it is held by arms N N, fixed to the framing, which plate serves to keep the liber down in the comb after, it has been introduced therein by the dabbingbrush. The pulley D carries a weight, D@ serving to balance more or less the weight of the eccentric or crank and parts attached.

The advantages attained by this invention are* First. The brush can be made of considerably smaller Size than heretofore, thus effecting IOO a great saving in cost, and it will also be less liable to become deteriorated by use and consequently last much longer.

Second. By preventing the wool or other ber from rising out of the comb after it has been dabbed in by the brush the perfect action of the combs on all parts thereof isinsured, resulting in a produce of superior quality.

Third. There is much less Wear and tear in the machine than in ordinary machines on aecount of the reduction of shocks and vibra tion. The brush being very much smaller, it exercises a greatly-reduced impact upon the combs, While at the same time the pressing of the ber into the combs is effected more or less gradually `by the said plates, instead of requiring to be effected entirely and suddenly by the force of the brush, as at present.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. rlhe outer comb of a Noble Wool-combing machine and the series of blades G, curved at their lower edges and Working in said comb, and a iixed pivot, G', on which the rear ends of the blades are mounted, and placed to hold the rear ends of the blades always within the comb, in combination with the frame of the machine, the crank C', and the connecting-rod F, connecting the crank C to the blades, substantially as described. y

2. The blades G, mounted at their rear ends upon a fixed pivot, the outer comb, in which the said blades Work, and the dabbing-brush K, in combination with the crank C', connecting-rod F, eccentric J, rod K, to which the brush is attached, and the connecting rod which connects the eccentric with the said rod K, for operating the dabbing-brush, substan- 4o Witnesses:
